You just need to gather all those subscribe and unsubscribe messages to a couple of folders applying some rules and using the scripts we wrote for adding or deleting addresses from a Mac OS X Mail (or Entourage folder). They are called ‘Adding recipients from Mac OS X Mail’ and ‘Deleting recipients from Mac OS X Mail’ (we also include Entourage and Powermail scripts). Those scripts come with MaxBulk distribution, inside the example\/AppleScript\/Mac OS X Mail import folder and are also accessible from both the import menu and import button. They are very easy to modify if you need to and automatically process a given Mail folder and take the From and Reply-To headers using their contents to add\/remove the addresses from the currently selected MaxBulk list.<\/p>\n
Also note that users may have several addresses and sometimes forwards so the e-mail used when replying will not always match the one used for receiving your message. The trick here is to add a [E-mail Address]<\/b> tag to your unsubscribe link this way:<\/p>\n
